WaterThe Betonica macrantha, commonly known as Large Betony, prefers consistent moisture, but it's important not to over-water as it can lead to root rot. Water the plant when the top inch of soil becomes dry, which typically equates to once every week, but this can vary depending on humidity and temperature conditions. A deep watering is recommended, allowing water to penetrate the soil to a depth of at least several inches. Depending on the size of the plant and pot, this may translate to around 16 to 32 ounces of water for indoor potted plants or 1 to 2 gallons for outdoor plants in dry conditions.
LightLarge Betony thrives best in full to partial sunlight. Hence, a spot that receives at least 4 to 6 hours of direct sunlight a day is ideal. However, it can also tolerate some shade, especially during the hottest parts of the day, to prevent scorching of the leaves. Adequate light will ensure vigorous growth and optimal flowering.
TemperatureLarge Betony fares well in a wide range of temperatures, but it is best suited to temperate climates. It can withstand minimum temperatures down to around 20°F and maximum temperatures of around 90°F. However, the ideal growing conditions for Betonica macrantha would be in temperatures ranging from 60°F to 80°F.
PruningPruning of Large Betony is generally done to maintain shape, remove dead or damaged foliage, and encourage bushier growth. It is best to prune in late winter or early spring before new growth begins. Cutting back the plant by about one-third every year helps rejuvenate and stimulates more prolific blooming. Deadheading spent flowers can also promote a second bloom in the fall.
CleaningNot needed
SoilGiant hyssop (Betonica macrantha) prefers well-draining soil with a mix containing equal parts garden soil, compost, and perlite or sand. The ideal soil pH for giant hyssop is around 6.0 to 7.5, slightly acidic to neutral.
RepottingGiant hyssop, also known as Betonica macrantha, should be repotted every 2-3 years to ensure it has enough space to grow and to refresh the soil nutrients.
Humidity & MistingGiant hyssop (Betonica macrantha) is not particularly humidity sensitive but thrives best in average room humidity levels around 40-60%.
Suitable locationsIndoor
Place giant hyssop in a bright spot, water when dry.
Outdoor
Plant in full sun to partial shade, well-drained soil.

Life cycleThe life cycle of Betonica macrantha, commonly known as Large Betony, begins with seed germination, typically occurring in spring when soil temperatures rise and moisture is adequate. The seedlings develop into rosettes of foliage at the ground level, with the leaves growing larger as the plant matures. In subsequent years, the Large Betony progresses from the vegetative stage to reproductive maturity, sending up flowering stalks that can reach up to 70 cm in height and display dense spikes of deep blue or purple flowers in the high summer. Pollination is mainly facilitated by bees and butterflies, which are attracted to the vibrant flowers. After pollination, the plant produces small nutlets, which are the seeds that will disperse to give rise to new plants. With the approaching autumn, the aerial parts of the plant die back, and it enters a period of dormancy over winter, with the root system surviving underground to sprout anew in the next growing season.
PropogationPropogation time
Spring to summer
Betonica macrantha, commonly known as Large-flowered Betony or Big Betony, is most commonly propagated through division, a method best performed in the spring or early fall. To propagate by division, carefully dig up an established clump of betony after the plant has finished blooming or before new growth starts. Using a sharp spade or knife, divide the clump into smaller sections, each with several shoots and a portion of the root system. Each division should be replanted immediately at the same depth it was growing at before, spaced approximately 12 inches (30 centimeters) apart to allow for growth. Ensure the soil is well-draining and keep the divisions well-watered until they are established. This encourages new root development and reduces transplant shock, allowing the plant to continue thriving and producing its attractive spikes of violet blooms.
